Detailed description of the invention
Below, by reference to the accompanying drawings, structure of the present invention and operation principle etc. are further described.
As shown in Figure 2,3, the present invention is a kind of mould manufacturing vacuum interrupter encapsulating for encapsulate injection technique, the front mould 6 comprising rear mold 5 and removably connect with rear mold 5, rear mold 5 and front mould 6 form die cavity 1, in mould, the position at contiguous die cavity 1 two ends is respectively arranged with the first groove 2 and the second groove 3, the second slide block 14 being provided with the static contact 1002 for fixing vacuum interrupter in the first slide block 4, second groove 3 for the moving contact 1001 of fixing vacuum interrupter is provided with in first groove 2.First slide block 4 and the second slide block 14, as a part for mould, can play the effect of fixing moving contact 1001, static contact 1002, and die cavity 1 are sealed to the effect that prevents injecting fluid from flowing out.The wall that front mould 6 corresponds to the first groove 2 and the second groove 3 is respectively arranged with installing hole 7, be provided with ejecting mechanism in installing hole 7, ejecting mechanism comprises thimble 8 and is positioned at thimble 8 rear end (namely thimble is away from one end of rear mold 5) and can applies elastic acting force to thimble 8 thus make thimble 8 extend out to the elastic component of the first slide block 4 or the second slide block 14.During use, the thimble 8 of this ejecting mechanism can withstand on the first slide block 4 and the second slide block 14 always, so that can prevent vacuum interrupter from encapsulating when die sinking mobile.
As shown in FIG., die cavity 1 is formed by front mould 6 and rear mold 5, mould position that is interior, that be positioned at die cavity 1 two ends is respectively arranged with the first groove 2 and the second groove 3, this first groove 2 and the second groove 3 respectively can accommodating first slide block 4 and the second slide blocks 14, and limit it and move, then by screw 11, vacuum interrupter moving contact 1001 and static contact 1002 are separately fixed on the slide block at die cavity 1 two ends.When matched moulds or die sinking, can by means of the mechanism for assembling-disassembling 12 of side by screw 11 dismounting, mechanism for assembling-disassembling 12 one end is provided with handle 13.
Elastic component can select conventional all multimodes, and preferred as one, the elastic component in the present invention is helical spring 9.
Helical spring 9 can be set to the diameter that diameter is less than thimble 8, and the rear being placed on thimble 8 rear end can apply elastic acting force to thimble 8.Preferred as one, thimble 8 comprises column 801, and the centre position of column 801 length direction is provided with flange 802, and helical spring 9 is sleeved on column 801 and is resisted against on flange 802.This structure, makes helical spring 9 stablize, prevents thimble 8 from pushing up partially.
Front mould 6 can be integral type structure, and installing hole 7 is formed by offering a blind hole on front mould 6.For limiting the moving range of ejecting mechanism, prevent it from rocking, to ensure that thimble 8 can just to the first slide block 4 or the second slide block 14 when stretching out further, front mould 6 in the present invention adopts dismountable split-type structural, makes installing hole 7 and ejecting mechanism form the structure being similar to cylinder body and coordinating with piston rod.That is, front mould 6 comprises the front mould body 601 that directly contacts with rear mold 5 and is positioned at front mould body 601 side and forms with front mould body 601 the front mould top board 602 removably connected, and installing hole 7 is arranged in front mould body 601 and front mould top board 602; Installing hole 7 comprise diameter be greater than the first hole section 701 of flange 802 diameter and diameter is less than flange 802 diameter, the second hole section 702 of extending out to the first slide block 4 or the second slide block 14 for column 801.The aperture of the first hole section 701 is greater than flange 802 diameter so that flange can move back and forth in the first hole section 701, and the aperture of the second hole section 702 is less than flange 802 diameter and is greater than column 801 diameter, so that column 801 can stretch out from the second hole section 702.
To sum up, the mould manufacturing vacuum interrupter encapsulating for encapsulate injection technique of the present invention, by arranging ejecting mechanism on front mould 6, when can prevent die sinking, vacuum interrupter 10 moves because of front mould 6 die cavity suction, prevent vacuum interrupter moving contact 1001 and static contact 1002 flexural deformation, the quality of the vacuum interrupter formed after effectively ensure that encapsulate encapsulating.
More than for the present invention is used for the structure of mould and the explanation of operation principle that encapsulate injection technique manufactures vacuum interrupter encapsulating; but those skilled in the art will recognize that under the teachings of the present invention; when not departing from essence of the present invention; can put into practice various change and distortion, it all falls into protection scope of the present invention.
